摘　　要：反手性拓扑光子态是具有抗背向散射及免疫缺陷特性的新型波导态,其在拓扑光子晶体的两个平行边界沿相同方向单向传输,在拓扑激光、集成光路、量子信息等领域展示出应用潜力。本文聚焦反手性拓扑光子态研究进展,从Dirac模型出发,推演经典Haldane模型、反手性Haldane模型以及异质Haldane模型,并展示不同拓扑态的传输行为。讨论手性边界态、反手性边界态以及单向体态在光子晶体中的实现,重点介绍基于反手性拓扑光子态的紧凑单向波导、拓扑环形腔、拓扑分束器等拓扑光学器件。最后针对反手性拓扑光子态研究面临的关键问题、未来发展趋势进行分析和展望。Antichiral topological photonic states are a new type of waveguide states that are robust against backscattering and immune to defects.They propagate unidirectionally in the same direction along two parallel boundaries of topological photonic crystal and show broad application potential in topological lasers,integrated optical circuits,and quantum information.This review focuses on the research progress in antichiral topological photonic states,starting from the Dirac model and derivation of the classical Haldane model,antichiral Haldane model,and heterogeneous Haldane model,which demonstrate the transmission behavior of different types of topological photonic states.In addition,the implementation of chiral edge states,antichiral edge states,and one-way bulk states in photonic crystals is discussed.Next,the construction of topological optical devices based on antichiral topological photonic states,such as compact unidirectional waveguides,topological ring cavities,and topological beam splitter,are introduced.Finally,the critical issues and future development trends in research on antichiral topological photonic states are analyzed.
